I noticed my CH was low last week (200). I added about 12lbs of Calcium Hardness increaser and it's sitting around 275 now. My wife was wondering why I needed to increase the water hardness, since everyone in our area complains about how hard the water is out of the tap. So I checked the tap water for CH and it's about 175 (no water softener at the house). It must be other minerals in the water that make it hard. Is there any concern about total hardness or other minerals getting high in the water? We tend to have a chalk or film on our tile above the waterline most of the time. The pool was first filled on 7/8. Below is the last test log.
